Toothbrush



FIG. 1 is a front elevational view of a toothbrush showing our new design; and,

FIG. 2 is a bottom, front, left side perspective view of the toothbrush feature of FIG. 1.

The claim is limited to the two oblong areas shown in solid lines. The dash-dot-dash line represents a boundary line and the dashed lines illustrate portions of the toothbrush that, along with said boundary, form no part of the claimed design. 

We claim the ornamental design for a toothbrush, as shown and described.
